To all whom t may concern.'

Be it lrnown that I, JASPER PATTERSON, a citizen of the United States, and a resident of Versailles, in the county of Brown and State of Illinois, have invented an Improvement in Silo-Roofs, of which the following is a specification.

My present invention relates generally to silos, and more particularly to the construction of the upper portion thereof including the roof arranged in sections to permit of opening and closing the same and a knockdown structure to constitute when erected a vertical continuation of the silo chamber, my object being to provide certain novel details in the construction and arrangement of these parts and tending to promote strength, durability and effectiveness in the instances to be hereinafter particularly referred to and described.

In the accompanying drawings which illustrate my invention,

Figure 1 is a perspective view of the upper portion of the silo showing the roof sections closed.

Fig. 2 is a similar view showing the roof sections open.

Fig. 3 is a vertical transverse section taken therethrough with the roof sections in opened position and the cylindrical receiving frame disposed in operative position.

Fig. 4 is a horizontal section taken therethrough substantially on line 4 4 of Fig. 3. Fig. 5 is an enlarged section through the enga-ging portions of adjacent roof sections in closed position.

Fig. 5a is a horizontal section through several of the roof sections in closed position. Fig. 6 is a vertical section taken through the parts in the position shown in Fig. 1.

Fig. 7 is a perspective view of a portion of the roof supporting frame with certain of its connections and illustrating one of the roof sections in open position. f

Fig. 8 is a fragmentary detail illustrating in perspective a portion of the silo wall and the lower end of the upright of a hoisting arrangement connected thereto.

Fig. 9 is a perspective view of the lower portion of one of the roof sections looking at the inner side thereof, and

Fig. 10 is a perspective view of the lower outeiportion of one of the lateral braces of the upright of the hoist.

Referring now to these gures, I preferably provide the usual cil-:cular Wall A of a edges,

silo with a plurality of spaced vertical slots extending radially with respect to the center of the silo chamber and adapted to receive a plurality of bracket bars B, having laterally projecting studs b at their inner ends to engage the inner surface of the silo wall as may be seen in Figs. 8 and 6 and having apertures adjacent their outer ends to receive the upper ends of hook bolt-s B, the lower ends of which are secured by suitable fastening members at Z9 around the outer surface of the silo wall as clearly seen in Figs. l, 2 and 6.

Each of the several triangular roof sections O consists of a-triangular frame C having an outer sheet metal covering C2 and the edges of the sheet metal coverings C2 are bent so as to lap one another throughout the series when the several sections C are closed as most clearly seen in Figs. 1 and 4:, one of the roof sections as clearly seen in Figs. l, 3 and 6 being provided with a conical cap G3 arranged to sit upon the smaller upper ends of the several sections in closed position. In order to permit of complete lapping of the edges of the roof sections throughout the series, one of said sections GO, will of necessity have two overlapping edges, and one section CX, two underlapping as seen by reference to Fig. 5a, the conical top C3 being carried by the section CO.

The enlarged lower ends of-the several roofsections are hinged to the several faces of a polygonal roof frame D, by hinges c, the leaves of which hinges, connected to the polygonal frame D are slotted to receive fastening members in order that each of the roof sections C may be adjusted within the limits of these slots to insure their relative it under varying conditions.

rlhe polygonal frame D is disposed above and aroundthe upper edge of the silo wall A and is seated upon the outer ends of the bracket bars B and connected thereto by depending bolts D having lower hook ends engaging the bracket bars B as best seen in Figs. l6 and 7.

The frames C of the several roof sections C are also provided with screw eyes c and to one of the screw eyes of each of the roof sections is connected a hook rod C4 for engagement with one of the screw eyes of the next adjacent roof section in one direction, thus providing for the connection of the entire set 0f roof Sections in Open position,

wall A are also secured a series of curved"VV metal plates A', the upper edges of which project above the upper end of the silo wall and thus form an annular space A2 between the same and the inner edge of the roof frame D in which space A.2 is adapted to rest the lower edge of a cylindrical eXtension wall or frame E, projecting upwardly within the opened roof sections C and so disposed when the said root sections are in open position, as clearly seen inFigs. 3 and 4.

This extension wall or frame E consists of a plurality of upright strips or staves supported together in proper position for the filling of the silo by means of surrounding circular wire hoops E having adjustably connected ends as seen at e in Fig. 2 and supported in spaced relation around the several upright strips or staves of the frame or wall E by means of hooks e2 disposed at certain points around the frame E in a vertical series, which hooks e2 are also linked together as clearly shown in Fig. 7 and the upper one thereof connected to one of the roof section screw eyes c. Each of the vertical strips or staves of the wall or frame E is also provided at its upper edge with a U-shaped clasping member e adapted to clasp the samev in connection with the upper circular hoop E as clearly seen in Fig. 3 in order that the several strips or staves may be held in proper position when initially inserted and before the circular hoops E are tightened therearound.

The extensionfranie or wall E thus provides a space forming a vertical extension of the chamber of the silo itself and permits the latter to be lled to such a point as to provide for shrinkage and settling due to fermentation to a point approximately level with the upper end of the silo wall A. When the material has shrunk and settled to this point the several hoops E are loosened and their supporting hooks e2 disengaged therefrom to permit the hoops to drop into the annular space A2 or adjacent thereto as seen in Fig. 2, the several strips or staves of the extension wall or frame E being thenl removed.

As seen in Fig. l, one of the roof sections C is provided with a transparent section c2 forming a window or sight opening and another of the sections adjacent thereto is provided with a sliding door c3 normally held in closed position by hooks 04 as shown in Fig.y 9 which may be turned to1 permit the door 03 to be removed.

In their closed positions the several sections C of the. roof rest upon a triangular supporting frame formed by three nllld beams G, the upper ends of which are connected together by a bolt g, and the lower ends of which are connected to a plurality of horizontal beams G one of which extends across the upper end of the silo, and the `hers of which are adapted to bel disposed radially upon the upper end of the silo wall A with their outer ends resting thereupon and their inner free ends supported by looped chains G2 the upper ends of which are connected to a shackle g depending from the bolt g. These several beams are placed in position within the upper portion of the silo as clearly shown in Figs. 2 and 6 when the extension wall or irame E is knocked down and the horizontal radial beams G form a support upon which the several wall strips or staves may be laid when detached if it is so desired. The inner ends of the several horizontal beams G being unconnected and supported merely by the depending chains G2, with the exception of the single straight beam mentioned above,

these several beams may be readily folded and the inclined beams G folded therewith, the latter being loosely connected at their' upper ends by the bolt g before mentioned, thus providing for the ready removal of these several beams when the roof sections are opened and the silo is to be filled.

I also provide a hoist for raising and lowering the usual blower pipe and distributer pipe used in illing the silo and including an upright H, the lower end of which is stepped in a cut out portion in the upper edge of the .f

silo wall A and provided with an adjustable depending hook bolt it for engagement with one of the radial roof 'frame supporting bars B as clearly seen in Fig. S. This uprightT-I has an upper swinging frame H which flexiblysupports a depending pulley L, and is braced by inclined lateral beams H2, the lower ends of which have angular foot plates h2 as best shown in Fig. 10, which may be bolted to the roof supporting frame D by bolts b3 as shown in F igs, 3 and 4. This hoist arrangement is erected after the roof sections have been opened and during the other preparations for loading or filling the silo including the erection of the eXtension wall or frame A.

Thus from the foregoing it will be seen that I provide a strong, durable and effective arrangement by which provision is made for opening the roof of a silo and readilyv tinuation of the silo chamber, may be rigidly and firmly held in position upon the silo without the utilization of the silo roof sections as a@ part of the support of such extension wall or frame, thus doing away with the danger of marring or injuring the roof sections and the lapping edges of their metal covers.

I claim:

1. A silo having an extension wall or frame adapted to be disposed upon the upper end of the silo consisting of a plurality of upright strips or staves, a plurality-of circular hoops having adjustably connected ends and adapted to closely surround the strips or staves to hold the same in position, and a U-shaped clasping member carried by each of the strips or staves to engage one of the hoops in order to support each strip or stave as the series thereo1 are being placed in position.

2. A silo provided with a plurality of triangular' hinged roof sections to form a pyramidal roof which may be opened and closed, each of the said roof sections being provided with screw eyes and with hook rods for engagement with the screw eyes to hold the roof sections in open position, an extension wall or frame for disposal upon the upper end of the silo when the roof sections are open, circular supporting hoops having adjustably connected ends for surrounding the extension wall to hold the latter in position, and series of interengaging hooks carried by certain of the roof sections and for engagement with the several supporting hoops of the extension wall to support the hoops in vertically spaced relation.

3. A silo provided at its upper end with a plurality of vertical slots spaced therearound, a plurality of upwardly projecting horizontal bars disposed in the slots and extending outwardly from the upper end of the silo wall, a polygonal rooi:l frame disposed upon the outer portions of the said ars, hook bolts depending from the frame and engaging the bars to securely hold the roof frame therearound, and a plurality of triangular roof sections hinged to the roof frame and forming a pyramidal roof which may be opened and closed, all substantially as described.
